Patent GB-2316699-A (GB)
Title: Hydrostatically actuated packer
Inventor: JORDAN JR HENRY JOE
IPC: E21B33/1295
Filed: 1997-08-29
Abstract: A packer is disclosed which uses applied pressure to set the slips and initiate a compressive force on the sealing elements 96. The compressive force applied to the sealing elements 96 moves components above the sealing element 96 to release a locking dog 108 and allows the available hydrostatic pressure in the wellbore to shift piston 122 and thus create an opposing force on the sealing elements 96 to ensure that they properly set. The sealing elements 96 are mounted directly to the packer body, thus eliminating a leak path from the fluid pressure application port which is located below the sealing elements 96 on the packer body. Various lock rings hold the set of the packer to avoid the creation of boost forces on the sealing elements 96 from applied or induced pressures from above or below the sealing elements 96. Movement of the body is not required to accomplish setting of this packer. In applications with low hydrostatic pressure, the annulus 156 can be pressurized to assist in obtaining the necessary pack-off pressure. The hydrostatic pressure continues to be available as a pack-off force even when the pressure below the packing element depletes as the reservoir depletes. The packing element, which is mounted directly to the packer body, eliminates leak paths behind it, while, at the same time, the packing element is set by opposed forces; i.e., hydraulic from below and hydrostatic from above.

Patent GB-2328437-A (GB)
Title: Process for the recovery of polyamide monomers involving filtration and depolymerisation of polyamide oligomers
Inventor: BUCHANAN KARL H
IPC: B01D29/11
Filed: 1996-06-06
Abstract: Polyamide oligomers obtained as a suspension in dilute aqueous solution are recycled in a two step process comprising (a) the combination of said oligomer solution with particulate high-molecular mass polyamide material to form a mass or matrix of polyamide and oligoamide material which is then (b) subjected to a depolymerisation step in order to release pure monomer material. Said aqueous oligomer solutions are usually obtained as a side product from the manufacture of polyamide polymers. The matrix of polyamide and oligoamide is preferably obtained by filtration where the particulate polyamide material is initially placed on the surface of the filter material to act as a filter aid and thus preventing the small molecular weight oligomers from clogging the pores of the fitter material. Upon completion of said filtration step, the material on the surface of the filter will be a mass of oligomers coated onto the polyamide particles. This material can then be removed, for example, by vibration or back-pulsing and the removed material can then be sent directly for depolymerisation. The monomer material obtained after depolymerisation can then be recycled back into the polyamide manufacturing step.

Title: Routing prefix allocation for mobile internet access
Inventor: VILANDER HARRI TAPANI
IPC: H04L12/56
Filed: 1999-03-31
Abstract: A method of allocating an Internet Protocol (IP) address to a mobile wireless terminal within a mobile telecommunications network. The network repeatedly broadcasts, over a radio broadcast channel of the network, a routing prefix corresponding to the Radio Network Controller (RNC) ID. Mobile terminals listen to the broadcast channel, either when registering with the network or subsequently thereto, to determine the routing prefix. A mobile terminal combines the routing prefix with a host part to generate an IP address for subsequent Internet sessions. The broadcast routing prefix may, instead of corresponding to the Radio Network Controller of a GPRS/UMTS network, may correspond to a node of the radio network, such as a Base Station Controller of a GSM network.

Title: Murine hybridoma-derived cell line producing monoclonal antibodies and a method of assaying leukocyte concentration in blood
IPC: C07K16/00
Filed: 1986-09-19
Abstract: A murine monoclonal antibody which selectively binds to the determinant site or specific epitope of glycophorin A exposed on the membrane of the erythrocyte and does not bind to other glycophorins. The monoclonal antibody is coated on a microsphere or substrate of a suitable monodispersed variety and utilized in a separation procedure for recovery of white blood cell subsets without lysing of erythrocytes. The bound microspheres are recovered without adverse depletion of the white blood cell population of the sample. The microsphere or bead-to-cell ratio employed is most acceptable for commercial applications of the invention. The invention thus enables accurate assaying of white blood cell subsets in circulating peripheral blood without resorting to lysing of erythrocytes.

Title: Insulation resistance measuring apparatus for electric line with suppressed stray capacity
Inventor: MATSUNO TATSUJI
IPC: G01R27/18
Filed: 1982-01-26
Abstract: PURPOSE:To enable a highly accurate measurement of insulation resistance under a hot-line condition in a wide range utterly irrelevant to stray capacity with a simple method. CONSTITUTION:An output of a zero phase current transformer ZCT is applied to a buffer BA via a low pass filter F and the output ig of the buffer is the sum of the current iR flowing through an insulation resistance and the current iC flowing through a stray capacity C, where iR<<iC. An output of an oscillator OSC, V=V0 sinomega0t undergoes a 90 deg. phase shifter PS and an inversion circuit INV to obtain an output current i=-acosomega0t. The outputs ig and i are added with an adder ADD, the output of which is applied to one input end of a multiplier MULT1. The output V2cosomega0t of the preceding phase shifter PS is applied to the other input end of the multiplier MULT1. Therefore, the output of the MULT1 provides a signal as represented by (ig+i)V2cosomega0t which is applied to an LPF1 to obtain the DC component (omega0CV0-a)V2/2. A VR is adjusted to render the output zero and a multiplier MULT2 extracts the DC component with an LPF2. Thus, V0V2R is obtained at the output thereof as a value reversely proportional to the insulation resitance.

Abstract: PROBLEM TO BE SOLVED: To suppress the generation of defects like electrical short circuit and realize improvement in yield, by regulating the quantity of conductive paste adhered to an upper side electrode to an appropriate level. SOLUTION: In this manufacturing method, a conductive paste 3 is supplied to a cut-out groove 5 of a paste supply body having the cut-out groove 5 formed on the surface, and then a collet pin 1 is impregnated with the conductive paste 3 in the cut-out groove 5, thereby adhering the conductive paste 3 to the collet pin 1. By causing the collet pin 1 to contact with a semiconductor chip via the conductive paste 3 adhered to the collet pin 1, the semiconductor chip is picked up. The semiconductor chip thus picked up is die-bonded onto the island of a lead frame. In this case, the cut-out groove 5 is formed in an inclined shape in advance so that its depth changes, and the collet pin 1 is impregnated with the conductive paste 3 until the collet pin 1 contacts the bottom surface of the cut-out groove 5 in a state where the depth of impregnation with respect to the cut-out groove 5 is set.
